Hiding a gray scale image encounters some difficulties. In this paper, a DCT-based image hiding algorithm is proposed. The bit rate of the hidden image is reduced by applying an image compression technique. To extract the hidden data from the corrupted watermarked image, BCH coding and matched filtering are applied. With the proposed algorithm, we hide a gray scale image of 64×64×8 in an image of 512×512×8. The experimental results demonstrated that the embedded image can be extracted reliably from noisy watermarked images
